acts like a single uncut section in conveying control energy to the train. rllhus while a train is in either partof the cut section7 it is properly protected against atrain ollowingr.

The ring' core 24 is placed around the axle Q5., and. when an interrupted periodic cur rent is used (as distinguished from an alten nating periodic current) the core 2l is prefcrablyI provided with an air gap, as showng to reduce possible objectionable etlects of residual magnetism. llhc ring core is 'preterably laminated and has a duplex winding composed of wires a and b wound in parah lel. The resonating relay 26 has also a sixnilar winding compose-d voi. wires c and d.

The connections of them windings will best be' understood by referring to Fig'. 5. The winding c and the winding b oit the secondary are here shown separately joined to the copper bar c at 27 and Q8. The two windings are supplied with continuelle current from battery 29 and since the winding a. and winding l) constitute a duplex winding.I the current from battery 29 will have no niagnetizing effect. rlfhe winding ot' the resonating relay 26 is also shown separated and the respective windings r] and e of this relay are joined. to the same copper bar c at 30 and 31. The resonating relay winding is also supplied with current from battery Q9 and, since the windings and e are parallcl, the magnetic effects of the current sup plied from battery 29 will be nulliied. lt is desirable that the magnetic eii'ects should bc 'mil normally in the windings oi. the resM coatingr relay, as well as in the windings of the ring core 24. Such a condition can be broughtl about when the current in the winding' nl is equaland opposite. to the cui rent in the winding @fand the current in winding:r rz. is equal and opposite to the cur rent in winding' l). This condition is made to exist by so arranging thewindings on the core 2l and. the windings on the resonatinff. relay that normally there is no battery current flowing `from K to l2 or from L to K, 'it will be seen'that long as this condition of electrical equilibrium exists there will also be a magnetic balance in the windings oi' the rcsonatinc` .relay as well as inV the windings of the core 2l. The battery current will flow through the circuits as.

shown by the arrows drawn in the windings. The periodic current (lowing` through the axle (which axle constitutes the primary oli a translriner) will induce an alternating ll. ill, l", in thcwinding's ot' core '24, that is in the windings e and l), these being" in parallel. the E. M. F. in these two windings will be equal and parallel. llherct'orc. there 'an bc no Flow ot current duc to this induced l. lli. ll. through the battery 29 and the only i 'ay'this ind uccd l?. can produce a flow ot current will be through the windings of resonating relay 26. it a direction for thisA alternating -current at any instant be assumed it will tlow as shown by the dotted arrows. Although the battery current through the resonatiiu` relay' windings flows in the two windings d and e, the current due to the induced alternating F. MQF. will at vany instant* flow in the saine direction in both ot the windings of rcsonating relay 26, with the not result that the fluxes due to the battery current nullity each other whereas the fluxes due to the alternating; current aid each other. rlhe rcsonatingrelay consists of a pernianent'mae'net which is split at 32, providing like poles shown at N and N and a pole tl ot polarity as shown. The tuned 'reed 33 is placed between the two like poles and since the poles are normally of the same strength this reed will be undisturbed. fis soon as tuned current is supplied to the j relay windings, that is a current '.rciniency the saine as the naturah period oli vibration ot' the reed 355, the reed will be thrown into vibration, open-cir- -cuiting the magnet 3lthrough the contacts 35 and Elli. Magnet' 3lwill remain denergized. because the reed 33 has a period ot' vibration greater than that of the Yibrating contacts 35, 3G, so that there will always be an open circuit between the reed 33, when Vibrating, and the contacts 3G. As soon as the tuned current. is withtlia\vn"ironi the windings of resonating relay 26, the vreed will come to a stop, again closing the circuit ot magnet i lt now a signal ot' different character is desired to be transmitted to the train at a given. location then a tuning iork l0 or reed having ay different 'frequency not an even harmonic oi the other tuning forks or tuning; reeds used along' the right ot wayl from the other tuning' torlts is placed in the circuit oli thetracli battery tix and another reed 37 whose natural `period ot \'ibrat'ion will corresigornl to that ot the het'orenicntioned tuning 'fork l0 is placed in the resonating relay 526i This reed 37 will control the circuit o mlasrnet 3S so that when the train reaches thel ocation where this tuning' fork or tuning; reed is placed the tuned current sent 'to the windings of the reso-nating relay 26 will at this time be such that no other reed in the rcsonating relay will spend to it lout the particular one, that is 37., operating inaenet thus giving; the desired signal or action on thefbraltcs. As herein shown7 'the tuningforli' vibrator l0 will be set into 'vibration when a train reaches block X. and. the lnannet llt' is dclnergrized by the opening' oli switch when a. track switch C in block ll is sct so as to run the train onto another track.
